HYDRAULIC DAMPING CONTROL SYSTEM IN ARTICULATED BUS AND CORRESPONDING BUS ARTICULATION SYSTEM

Disclosed are a hydraulic damping control system in articulated bus and a corresponding bus articulation system , the hydraulic damping control system comprises a front frame (1), a rear frame (2), a sensing device (61,62;81,82) and a hydraulic damping device, wherein the front frame (1) rotates relative to the rear frame (2); the sensing device (61,62;81,82) are used for detecting the relative rotation angle between the front frame (1) and the rear frame (2), the hydraulic damping device provides damping control for the front frame (1) and the rear frame (2) according to values of the angle detected by the sensing device (61,62;81,82); and in the bus articulation system, the transmission between the front frame (1) and the rear frame (2) articulation system is conducted via rotating components (101,102) and a single sliding component (3). The bus articulation system for carrying out hydraulic damping control which adopts this structure articulation system can achieve multi-damping control only by adopting a gear rack transmission structure, so that the structure is compact and the space of articulation system is saved further, A hydraulic damping device is provided in an integrated block, so that the multi-damping control design enables the damping between the front frame and the rear frame to be different when the relative rotation angles between the front and rear frame are different; The hydraulic damping device is safe in use, and may not cause danger even if the system loses power.
